What is vbAnonymizer?
vbAnonymizer is a vBulletin modification which prevents the referrer headers from being sent when visiting off-site links.

Why do we need to do this?
We need to do this because some sites track the referrer header, which means they know where the visitor came from. To protect the boards privacy, this modification is being used.

How did I get here?
You clicked on "vbAnonymizer" next to "Visiting Link" in a users profile. You also may have clicked an invalid URL being redirected.
